Definitions

  • Apoptosis or programmed cell death, is a conserved and regulated process that is the primary mechanism for the removal of aged, damaged and unnecessary cells.
  • the ability to block apoptotic signaling is a key hallmark of cancer and is thus important for oncogenesis, tumor maintenance and chemoresistance [Hanahan, D. & Weinberg, R.A. The hallmarks of cancer. Cell 100, 57-70 (2000).].
  • BCL-2-associated X protein for example, BCL-2-associated X protein (BAX), BCL-2 antagonist/killer 1 (BAK), BCL- 2- associated agonist of cell death (BAD), BCL- 2-like 11 (BIM), NOXA and BCL-2 binding component 3 (PUMA)
  • prosurvival BCL-2, BCL- XL, BCL- 2-like 2 (BCL-W), myeloid cell leukemia sequence 1 (MCL-1) and BCL-2-related protein A1 (BFL-1)
  • Altering the balance among these opposing factions provides one means by which cancer cells undermine normal apoptosis and gain a survival advantage [Youle, R.J. & Strasser, A. The BCL-2 protein family: opposing activities that mediate cell death. Nat. Rev. Mol. Cell Biol. 9, 47-59 (2008)].
  • BCL-2 the first identified apoptotic regulator, was originally cloned from the breakpoint of a t( 14; 18) translocation present in human B cell lymphomas [Tsujimoto, Y., et al. Science 228, 1440-1443 (1985); Cleary, M.L., et al Cell 47, 19-28 (1986); Boise, L.H. et al. Cell 74, 597-608 (1993)].
  • This protein has since been shown to have a dominant role in the survival of multiple lymphoid malignancies [Vaux, D.L., et al pre-B cells. Nature 335, 440-442 (1988)].
  • BCL-2 proteins correlates with resistance to chemotherapy, clinical outcome, disease progression, overall prognosis or a combination thereof in various cancers and disorders of the immune system.
  • BCL-2 proteins in immune and autoimmune diseases are described in Current Allergy and Asthma Reports 2003, 3, 378-384; British Journal of Hematology 2000, 110(3), 584-90; Blood 2000, 95(4), 1283-92; and New England Journal of Medicine 2004, 351(14), 1409-1418.
  • Involvement of BCL-2 proteins in arthritis is disclosed in WO 2009/064938.
  • Involvement of BCL-2 proteins in bone marrow transplant rejection is disclosed in US 2008-0182845 A1. All incorporated herein by reference.

This International Patent Application claims the benefit of the filing dates of U.S. Provisional Patent Application Nos. 62/909,958, filed on October 3, 2019, and 62/948,627, filed on December 16, 2019. The entire contents of each of the above-referenced applications are incorporated herein by reference.
BACKGROUND OF THE INVENTION
Apoptosis, or programmed cell death, is a conserved and regulated process that is the primary mechanism for the removal of aged, damaged and unnecessary cells. The ability to block apoptotic signaling is a key hallmark of cancer and is thus important for oncogenesis, tumor maintenance and chemoresistance [Hanahan, D. & Weinberg, R.A. The hallmarks of cancer. Cell 100, 57-70 (2000).]. Dynamic binding interactions between prodeath (for example, BCL-2-associated X protein (BAX), BCL-2 antagonist/killer 1 (BAK), BCL- 2- associated agonist of cell death (BAD), BCL- 2-like 11 (BIM), NOXA and BCL-2 binding component 3 (PUMA)) and prosurvival (BCL-2, BCL- XL, BCL- 2-like 2 (BCL-W), myeloid cell leukemia sequence 1 (MCL-1) and BCL-2-related protein A1 (BFL-1)) proteins in the BCL-2 family control commitment to programmed cell death. Altering the balance among these opposing factions provides one means by which cancer cells undermine normal apoptosis and gain a survival advantage [Youle, R.J. & Strasser, A. The BCL-2 protein family: opposing activities that mediate cell death. Nat. Rev. Mol. Cell Biol. 9, 47-59 (2008)].
BCL-2, the first identified apoptotic regulator, was originally cloned from the breakpoint of a t( 14; 18) translocation present in human B cell lymphomas [Tsujimoto, Y., et al. Science 228, 1440-1443 (1985); Cleary, M.L., et al Cell 47, 19-28 (1986); Boise, L.H. et al. Cell 74, 597-608 (1993)]. This protein has since been shown to have a dominant role in the survival of multiple lymphoid malignancies [Vaux, D.L., et al pre-B cells. Nature 335, 440-442 (1988)]. Overexpression of BCL-2 proteins correlates with resistance to chemotherapy, clinical outcome, disease progression, overall prognosis or a combination thereof in various cancers and disorders of the immune system. Involvement of BCL-2 proteins in bladder cancer, brain cancer, breast cancer, bone marrow cancer, cervical cancer, chronic lymphocytic leukemia, colorectal cancer, esophageal cancer, hepatocellular cancer, lymphoblastic leukemia, follicular lymphoma, lymphoid malignancies of T-cell or B-cell origin, melanoma, myelogenous leukemia, myeloma, oral cancer, ovarian cancer, non-small cell lung cancer, prostate cancer, small cell lung cancer, spleen cancer, and the like is described in PCT/US2004/36770, published as WO 2005/049593, and PCT/US2004/37911, published as WO/2005/049594. Involvement of BCL-2 proteins in immune and autoimmune diseases is described in Current Allergy and Asthma Reports 2003, 3, 378-384; British Journal of Hematology 2000, 110(3), 584-90; Blood 2000, 95(4), 1283-92; and New England Journal of Medicine 2004, 351(14), 1409-1418. Involvement of BCL-2 proteins in arthritis is disclosed in WO 2009/064938. Involvement of BCL-2 proteins in bone marrow transplant rejection is disclosed in US 2008-0182845 A1. All incorporated herein by reference. In the last decade, several BCL-2 inhibitors such as ABT-737, ABT-263, and ABT- 199 as shown below have been identified and entered human clinical trials for cancers treatment.
Figure imgf000003_0001
ABT-737 is discovered by nuclear magnetic resonance (NMR)-based screening, parallel synthesis and structure based fragment drug design [Tillman Oltersdorf, et al, Nature, Vol 435, 2005, p 677]. ABT-737 a small-molecule inhibitor of the anti-apoptotic proteins BCL-2, Bcl-XL and Bcl-w, with an affinity two to three orders of magnitude more potent than previously reported compounds. Mechanistic studies reveal that ABT-737 does not directly initiate the apoptotic process, but enhances the effects of death signals, displaying synergistic cytotoxicity with chemotherapeutics and radiation. ABT-737 exhibits single- agent-mechanism-based killing of cells from lymphoma and small-cell lung carcinoma lines, as well as primary patient-derived cells, and in animal models, ABT-737 improves survival, causes regression of established tumors, and produces cures in a high percentage of the mice. Unfortunately, ABT-737 is not orally bioavailable, and its formulation for intravenous delivery is hampered by its low aqueous solubility. After extensive MedChem effort, an orally bioavailable BCL-2 inhibitor ABT-263 (Navitoclax) has been developed [Cheol-Min Park, et al J. Med. Chem. 2008, 51, 6902– 6915]. ABT-263 is a potent inhibitor of Bcl-xL, BCL-2 and Bcl-w with Ki of ≤ 0.5 nM, ≤ 1 nM and ≤ 1 nM. ABT-263 has an IC50 of 110 nM against SCLC H146 cell line. When ABT- 263 is administered at 100 mg/kg/day in the H345 xenograft model, significant antitumor efficacy is observed with 80% TGI and 20% of treated tumors indicating at least a 50% reduction in tumor volume. Oral administration of ABT-263 alone causes complete tumor regressions in xenograft models of small-cell lung cancer and acute lymphoblastic leukemia [Tse C, et al. Cancer Res. 2008, 68(9), 3421-3428]. In the clinical trial, however, the inhibition of BCL-XL by ABT-263 (navitoclax) induces a rapid, concentration-dependent decrease in the number of circulating platelets. This mechanism-based thrombocytopenia is the dose-limiting toxicity of single-agent navitoclax treatment in patients and limits the ability to drive drug concentrations into a highly efficacious range. Thus, a BCL-2 selective (BCL-XL sparing) inhibitor would culminate in substantially reduced thrombocytopenia while maintaining efficacy in lymphoid malignancies. The resulting increase in the therapeutic window should allow for greater BCL-2 suppression and clinical efficacy in BCL-2–dependent tumor types. After extensive MedChem, ABT-199 (GDC-0199) has been successfully developed [Andrew J Souers, et al, Nature Medicine, Volume 19, 22, p202, 2013]. ABT-199 is a BCL-2-selective inhibitor with Ki of <0.01 nM, >4800-fold more selective versus Bcl-xL and Bcl-w, and no activity to Mcl-1. ABT-199 potently inhibits RS4;11 cells with EC50 of 8 nM. In addition, ABT-199 induces a rapid apoptosis in RS4;11 cells with cytochrome c release, caspase activation, and the accumulation of sub-G0/G1 DNA. Quantitative immunoblotting reveals that sensitivity to ABT-199 correlated strongly with the expression of BCL-2, including NHL, DLBCL, MCL, AML and ALL cell lines. ABT-199 also induces apoptosis in CLL with an average EC50 of 3.0 nM. A single dose of 100 mg/kg of ABT-199 causes a maximal tumor growth inhibition of 95% and tumor growth delay of 152% in RS4;11 xenografts. ABT-199 also inhibits xenograft growth (DoHH2, Granta-519) as a single agent or in combination with Bendamustine and other agents. Human Phase I and II data showed that ABT-199 is highly efficacious for CLL who have 17p deletion, and was approved by FDA in 2016. WO/2017/132474, WO/2019/040550, and WO/2019/040573 disclosed a novel class of BCL-2 inhibitors. However, there is still a strong need for continuing search in this field of art for more potent BCL-2 inhibitor.

Compounds of the invention may contain one or more asymmetric carbon atoms. Accordingly, the compounds may exist as diastereomers, enantiomers or mixtures thereof. The syntheses of the compounds may employ racemates, diastereomers or enantiomers as starting materials or as intermediates. Diastereomeric compounds may be separated by chromatographic or crystallization methods. Similarly, enantiomeric mixtures may be separated using the same techniques or others known in the art. Each of the asymmetric carbon atoms may be in the R or S configuration, and both of these configurations are within the scope of the invention. Compounds having one or more chiral centers can exist in various stereoisomeric forms. Stereoisomers are compounds that differ only in their spatial arrangement. Stereoisomers include all diastereomeric, enantiomeric, and epimeric forms as well as racemates and mixtures thereof. The term “geometric isomer” refers to cyclic compounds having at least two substituents, wherein the two substituents are both on the same side of the ring (cis) or wherein the substituents are each on opposite sides of the ring (trans). When a disclosed compound is named or depicted by structure without indicating stereochemistry, it is understood that the name or the structure encompasses one or more of the possible stereoisomers, or geometric isomers, or a mixture of the encompassed stereoisomers or geometric isomers. When a geometric isomer is depicted by name or structure, it is to be understood that the named or depicted isomer exists to a greater degree than another isomer, that is that the geometric isomeric purity of the named or depicted geometric isomer is greater than 50%, such as at least 60%, 70%, 80%, 90%, 99%, or 99.9% pure by weight. Geometric isomeric purity is determined by dividing the weight of the named or depicted geometric isomer in the mixture by the total weight of all of the geomeric isomers in the mixture. Racemic mixture means 50% of one enantiomer and 50% of is corresponding enantiomer. When a compound with one chiral center is named or depicted without indicating the stereochemistry of the chiral center, it is understood that the name or structure encompasses both possible enantiomeric forms (e.g., both enantiomerically-pure, enantiomerically-enriched or racemic ) of the compound. When a compound with two or more chiral centers is named or depicted without indicating the stereochemistry of the chiral centers, it is understood that the name or structure encompasses all possible diasteriomeric forms (e.g., diastereomerically pure, diastereomerically enriched and equimolar mixtures of one or more diastereomers (e.g., racemic mixtures) of the compound. Enantiomeric and diastereomeric mixtures can be resolved into their component enantiomers or stereoisomers by well-known methods, such as chiral-phase gas chromatography, chiral-phase high performance liquid chromatography, crystallizing the compound as a chiral salt complex, or crystallizing the compound in a chiral solvent. Enantiomers and diastereomers also can be obtained from diastereomerically- or enantiomerically-pure intermediates, reagents, and catalysts by well-known asymmetric synthetic methods. When a compound is designated by a name or structure that indicates a single enantiomer, unless indicated otherwise, the compound is at least 60%, 70%, 80%, 90%, 99% or 99.9% optically pure (also referred to as “enantiomerically pure”). Optical purity is the weight in the mixture of the named or depicted enantiomer divided by the total weight in the mixture of both enantiomers. When the stereochemistry of a disclosed compound is named or depicted by structure, and the named or depicted structure encompasses more than one stereoisomer (e.g., as in a diastereomeric pair), it is to be understood that one of the encompassed stereoisomers or any mixture of the encompassed stereoisomers is included. It is to be further understood that the stereoisomeric purity of the named or depicted stereoisomers at least 60%, 70%, 80%, 90%, 99% or 99.9% by weight. The stereoisomeric purity in this case is determined by dividing the total weight in the mixture of the stereoisomers encompassed by the name or structure by the total weight in the mixture of all of the stereoisomers. A modified compound of any one of such compounds including a modification having an improved (e.g., enhanced, greater) pharmaceutical solubility, stability, bioavailability and/or therapeutic index as compared to the unmodified compound is also contemplated. The examples of modifications include but not limited to the prodrug derivatives, and the deuterium-enriched compounds. For example: • Prodrug derivatives: prodrugs, upon administration to a subject, will converted in vivo into active compounds of the present invention [Nature Reviews of Drug Discovery, 2008, Volume 7, p255]. It is noted that in many instances, the prodrugs themselves also fall within the scope of the range of compounds according to the present invention. The prodrugs of the compounds of the present invention can be prepared by starndard organic reaction, for example, by reacting with a carbamylating agent (e.g., 1,1-acyloxyalkylcarbonochloridate, para-nitrophenyl carbonate, or the like) or an acylating agent. Further examples of methods and strategies of making prodrugs are described in Bioorganic and Medicinal Chemistry Letters, 1994, Vol. 4, p. 1985. • Deuterium-enriched compounds: deuterium (D or 2H) is a stable, non-radioactive isotope of hydrogen and has an atomic weight of 2.0144. Hydrogen naturally occurs as a mixture of the isotopes XH (hydrogen or protium), D (2H or deuterium), and T (3H or tritium). The natural abundance of deuterium is 0.015%. One of ordinary skill in the art recognizes that in all chemical compounds with a H atom, the H atom actually represents a mixture of H and D, with about 0.015% being D. Thus, compounds with a level of deuterium that has been enriched to be greater than its natural abundance of 0.015%, should be considered unnatural and, as a result, novel over their nonenriched counterparts. It should be recognized that the compounds of the present invention may be present and optionally administered in the form of salts, and solvates. The invention encompasses any pharmaceutically acceptable salts and solvates of any one of the above-described compounds and modifications thereof. For example, it is within the scope of the present invention to convert the compounds of the present invention into and use them in the form of their pharmaceutically acceptable salts derived from various organic and inorganic acids and bases in accordance with procedures well known in the art. When the compounds of the present invention possess a free base form, the compounds can be prepared as a pharmaceutically acceptable acid addition salt by reacting the free base form of the compound with a pharmaceutically acceptable inorganic or organic acid, e.g., hydrohalides such as hydrochloride, hydrobromide, hydroiodide; other mineral acids such as sulfate, nitrate, phosphate, etc.; and alkyl and monoarylsulfonates such as ethanesulfonate, toluenesulfonate and benzenesulfonate; and other organic acids and their corresponding salts such as acetate, tartrate, maleate, succinate, citrate, benzoate, salicylate and ascorbate. Further acid addition salts of the present invention include, but are not limited to: adipate, alginate, arginate, aspartate, bisulfate, bisulfite, bromide, butyrate, camphorate, camphorsulfonate, caprylate, chloride, chlorobenzoate, cyclopentanepropionate, digluconate, dihydrogenphosphate, dinitrobenzoate, dodecylsulfate, fumarate, galacterate (from mucic acid), galacturonate, glucoheptaoate, gluconate, glutamate, glycerophosphate, hemisuccinate, hemisulfate, heptanoate, hexanoate, hippurate, 2-hydroxyethanesulfonate, iodide, isethionate, iso-butyrate, lactate, lactobionate, malonate, mandelate, metaphosphate, methanesulfonate, methylbenzoate, monohydrogenphosphate, 2-naphthalenesulfonate, nicotinate, oxalate, oleate, pamoate, pectinate, persulfate, phenylacetate, 3-phenylproρionate, phosphonate and phthalate. It should be recognized that the free base forms will typically differ from their respective salt forms somewhat in physical properties such as solubility in polar solvents, but otherwise the salts are equivalent to their respective free base forms for the purposes of the present invention. When the compounds of the present invention possess a free acid form, a pharmaceutically acceptable base addition salt can be prepared by reacting the free acid form of the compound with a pharmaceutically acceptable inorganic or organic base. Examples of such bases are alkali metal hydroxides including potassium, sodium and lithium hydroxides; alkaline earth metal hydroxides such as barium and calcium hydroxides; alkali metal alkoxides, e.g., potassium ethanolate and sodium propanolate; and various organic bases such as ammonium hydroxide, piperidine, diethanolamine and N-methylglutamine. Also included are the aluminum salts of the compounds of the present invention. Further base salts of the present invention include, but are not limited to: copper, ferric, ferrous, lithium, magnesium, manganic, manganous, potassium, sodium and zinc salts. Organic base salts include, but are not limited to, salts of primary, secondary and tertiary amines, substituted amines including naturally occurring substituted amines, cyclic amines and basic ion exchange resins, e.g., arginine, betaine, caffeine, chloroprocaine, choline, N,N’-dibenzylethylenediamine (benzathine), dicyclohexylamine, diethanolamine, 2-diethylaminoethanol, 2- dimethylaminoethanol, ethanolamine, ethylenediamine, N-ethylmorpholine, N- ethylpiperidine, glucamine, glucosamine, histidine, hydrabamine, iso-propylamine, lidocaine, lysine, meglumine, N-methyl-D-glucamine, morpholine, piperazine, piperidine, polyamine resins, procaine, purines, theobromine, triethanolamine, triethylamine, trimethylamine, tripropylamine and tris-(hydroxymethyl)-methylamine (tromethamine). It should be recognized that the free acid forms will typically differ from their respective salt forms somewhat in physical properties such as solubility in polar solvents, but otherwise the salts are equivalent to their respective free acid forms for the purposes of the present invention. In one aspect, a pharmaceutically acceptable salt is a hydrochloride salt, hydrobromide salt, methanesulfonate, toluenesulfonate, acetate, fumarate, sulfate, bisulfate, succinate, citrate, phosphate, maleate, nitrate, tartrate, benzoate, biocarbonate, carbonate, sodium hydroxide salt, calcium hydroxide salt, potassium hydroxide salt, tromethamine salt, or mixtures thereof. Compounds of the present invention that comprise tertiary nitrogen-containing groups may be quaternized with such agents as (C1-4) alkyl halides, e.g., methyl, ethyl, iso-propyl and tert-butyl chlorides, bromides and iodides; di-(C1-4) alkyl sulfates, e.g., dimethyl, diethyl and diamyl sulfates; alkyl halides, e.g., decyl, dodecyl, lauryl, myristyl and stearyl chlorides, bromides and iodides; and aryl (C1-4) alkyl halides, e.g., benzyl chloride and phenethyl bromide. Such salts permit the preparation of both water- and oil-soluble compounds of the invention. Amine oxides, also known as amine-N-oxide and N-oxide, of anti-cancer agents with tertiary nitrogen atoms have been developed as prodrugs [Mol Cancer Therapy. 2004 Mar; 3(3):233-44]. Compounds of the present invention that comprise tertiary nitrogen atoms may be oxidized by such agents as hydrogen peroxide (H2O2), Caro’s acid or peracids like meta- Chloroperoxybenzoic acid (mCPBA) to from amine oxide. The compounds disclosed therein are inhibitors for Bcl-2 family proteins, such as Bcl- 2. For simplicity, the term “Bcl-2 inhibitor” includes compounds that inhibits one activity of at least one Bcl-2 family member, especially Bcl-2 family member with anti-apoptotic activity, such as Bcl-2. Bcl-2 family proteins have a general structure that consists of a hydrophobic α-helix surrounded by amphipathic α-helices. Some members of the family have transmembrane domains at their c-terminus, which primarily function to localize them to the mitochondrion. For example, Bcl-x(L) has 233 residues and exhibits a single highly hydrophobic putative transmembrane α-helical segment (residues 210-226) when in the membrane. Related family members include Bax and Bak, which also influence apoptosis. All members of the Bcl-2 family share one or more of the four characteristic domains of homology entitled the Bcl-2 homology (BH) domains (named BH1, BH2, BH3 and BH4). The BH domains are known to be crucial for function, as deletion of these domains via molecular cloning affects survival/apoptosis rates. The anti-apoptotic Bcl-2 proteins, such as Bcl-2 and Bcl-xL, conserve all four BH domains. Structural homology suggests that Bcl-2 family members that contain the BH1 and BH2 domains (Bcl-X(L), Bcl-2, and Bax) function similarly. On the other hand, the BH domains also serve to subdivide the pro-apoptotic Bcl-2 proteins into those with several BH domains (e.g. Bax and Bak) or those proteins that have only the BH3 domain (e.g., Bim, Bid, and BAD). All anti-apoptotic Bcl-2 family proteins (such as Bcl-2, Bcl-xL, Bcl-w, Mcl-1, CED- 9, A1, and Bfl-1) contain BH1 and BH2 domains, some of them contain an additional N- terminal BH4 domain (Bcl-2, Bcl-x(L) and Bcl-w), which is also seen in some pro-apoptotic proteins like Bcl-x(S), Diva, Bok-L and Bok-S. On the other hand, all pro-apoptotic Bcl-2 family proteins (such as Bcl-xS, Bax, Bak, Diva, Bik, Bim, BAD, Bid, and Egl-1) contain a BH3 domain necessary for dimerization with other proteins of Bcl-2 family and crucial for their killing activity, some of them also contain BH1 and BH2 domains (e.g., Diva, Bax and Bak). The BH3 domain is also present in some anti-apoptotic protein, such as Bcl-2 or Bcl- x(L). The three functionally important Bcl-2 homology regions (BH1, BH2 and BH3) are in close spatial proximity. They form an elongated cleft that may provide the binding site for other Bcl-2 family members. In certain embodiments, the compounds of the invention function as BH3 mimetic to inhibit the function of one or more Bcl-2 family members that are anti-apoptotic, such as Bcl- 2, Bcl-x(L), and/or Bcl-w, thus enhancing apoptosis (e.g., enhances an apoptotic signal). The pharmaceutical composition of the present invention comprises one or more BCL-2 inhibitors, or a pharmaceutically acceptable salt thereof, and a pharmaceutically acceptable carrier or diluent. “Pharmaceutically acceptable carrier” and “pharmaceutically acceptable diluent” refer to a substance that aids the formulation and/or administration of an active agent to and/or absorption by a subject and can be included in the compositions of the present disclosure without causing a significant adverse toxicological effect on the subject. Non-limiting examples of pharmaceutically acceptable carriers and/or diluents include water, NaCl, normal saline solutions, lactated Ringer’s, normal sucrose, normal glucose, binders, fillers, disintegrants, lubricants, coatings, sweeteners, flavors, salt solutions (such as Ringer’s solution), alcohols, oils, gelatins, carbohydrates such as lactose, amylose or starch, fatty acid esters, hydroxymethycellulose, polyvinyl pyrrolidine, and colors, and the like. Such preparations can be sterilized and, if desired, mixed with auxiliary agents such as lubricants, preservatives, stabilizers, wetting agents, emulsifiers, salts for influencing osmotic pressure, buffers, coloring, and/or aromatic substances and the like that do not deleteriously react with or interfere with the activity of the compounds provided herein. One of ordinary skill in the art will recognize that other pharmaceutical excipients are suitable for use with disclosed compounds. The pharmaceutical compositions of the present invention optionally include one or more pharmaceutically acceptable carriers and/or diluents therefor, such as lactose, starch, cellulose and dextrose. Other excipients, such as flavoring agents; sweeteners; and preservatives, such as methyl, ethyl, propyl and butyl parabens, can also be included. More complete listings of suitable excipients can be found in the Handbook of Pharmaceutical Excipients (5th Ed., Pharmaceutical Press (2005)). A person skilled in the art would know how to prepare formulations suitable for various types of administration routes. Conventional procedures and ingredients for the selection and preparation of suitable formulations are described, for example, in Remington’s Pharmaceutical Sciences (2003 - 20th edition) and in The United States Pharmacopeia: The National Formulary (USP 24 NF19) published in 1999. The carriers, diluents and/or excipients are “acceptable” in the sense of being compatible with the other ingredients of the pharmaceutical composition and not deleterious to the recipient thereof. The pharmaceutical compositions of the present invention may further comprise other conventional pharmaceutically inactive agents. Any inert excipient that is commonly used as a carrier or diluent may be used in compositions of the present invention, such as sugars, polyalcohols, soluble polymers, salts and lipids. Sugars and polyalcohols which may be employed include, without limitation, lactose, sucrose, mannitol, and sorbitol. Illustrative of the soluble polymers which may be employed are polyoxyethylene, poloxamers, polyvinylpyrrolidone, and dextran. Useful salts include, without limitation, sodium chloride, magnesium chloride, and calcium chloride. Lipids which may be employed include, without limitation, fatty acids, glycerol fatty acid esters, glycolipids, and phospholipids. In addition, the pharmaceutical compositions of the present invention may further comprise binders (e.g., acacia, cornstarch, gelatin, carbomer, ethyl cellulose, guar gum, hydroxypropyl cellulose, hydroxypropyl methyl cellulose, povidone), disintegrating agents (e.g., cornstarch, potato starch, alginic acid, silicon dioxide, croscarmellose sodium, crospovidone, guar gum, sodium starch glycolate, Primogel), buffers (e.g., tris-HCL, acetate, phosphate) of various pH and ionic strength, additives such as albumin or gelatin to prevent absorption to surfaces, detergents (e.g., Tween 20, Tween 80, Pluronic F68, bile acid salts), protease inhibitors, surfactants (e.g., sodium lauryl sulfate), permeation enhancers, solubilizing agents (e.g., glycerol, polyethylene glycerol, cyclodextrins), a glidant (e.g., colloidal silicon dioxide), anti-oxidants (e.g., ascorbic acid, sodium metabisulfite, butylated hydroxyanisole), stabilizers (e.g., hydroxypropyl cellulose, hydroxypropylmethyl cellulose), viscosity increasing agents (e.g., carbomer, colloidal silicon dioxide, ethyl cellulose, guar gum), sweeteners (e.g., sucrose, aspartame, citric acid), flavoring agents (e.g., peppermint, methyl salicylate, or orange flavoring), preservatives (e.g., Thimerosal, benzyl alcohol, parabens), lubricants (e.g., stearic acid, magnesium stearate, polyethylene glycol, sodium lauryl sulfate), flow-aids (e.g., colloidal silicon dioxide), plasticizers (e.g., diethyl phthalate, triethyl citrate), emulsifiers (e.g., carbomer, hydroxypropyl cellulose, sodium lauryl sulfate, methyl cellulose, hydroxyethyl cellulose, carboxymethylcellulose sodium), polymer coatings (e.g., poloxamers or poloxamines), coating and film forming agents (e.g., ethyl cellulose, acrylates, polymethacrylates) and/or adjuvants. In one embodiment, the pharmaceutical compositions are prepared with carriers that will protect the compound against rapid elimination from the body, such as a controlled release formulation, including implants and microencapsulated delivery systems. Biodegradable, biocompatible polymers can be used, such as ethylene vinyl acetate, polyanhydrides, polyglycolic acid, collagen, polyorthoesters, and polylactic acid. Methods for preparation of such formulations will be apparent to those skilled in the art. The materials can also be obtained commercially from Alza Corporation and Nova Pharmaceuticals, Inc. Liposomal suspensions (including liposomes targeted to infected cells with monoclonal antibodies to viral antigens) can also be used as pharmaceutically acceptable carriers. These can be prepared according to methods known to those skilled in the art, for example, as described in U.S. Pat. No. 4,522,811. Additionally, the invention encompasses pharmaceutical compositions comprising any solid or liquid physical form of the compound of the invention. For example, the compounds can be in a crystalline form, in amorphous form, and have any particle size. The particles may be micronized, or may be agglomerated, particulate granules, powders, oils, oily suspensions or any other form of solid or liquid physical form. When compounds according to the present invention exhibit insufficient solubility, methods for solubilizing the compounds may be used.

The counter ion may be any organic or inorganic moiety that stabilizes the charge on the parent compound. Furthermore, a pharmaceutically acceptable salt may have more than one charged atom in its structure. Instances where multiple charged atoms are part of the pharmaceutically acceptable salt can have multiple counter ions. Hence, a pharmaceutically acceptable salt can have one or more charged atoms and/or one or more counter ion. “Pharmacophore,” as defined by The International Union of Pure and Applied Chemistry, is an ensemble of steric and electronic features that is necessary to ensure the optimal supramolecular interactions with a specific biological target and to trigger (or block) its biological response.

Biological Example 1: BCL-2 Competition Binding (Fluorescence Polarization) Assay The fluorescence-labeled 23 amino acid peptide BH3 was purchased from CalBiochem (NLWAAQRYGRELRRMSDKFVD). An unbound Fluorescein labeled BH3 peptide emits random light with respect to the plane of polarization plane of excited light, resulting in a lower polarization degree (mP) value. When the peptide is bound to BCL-2, the complex tumble slower and the emitted light can have a higher level of polarization, resulting in a higher mP value. This binding assay was performed in 96-well plate and with each assay contained 15 and 30nM of labeled peptide and purified BCL-2 protein (purchased from R&D Systems, Inc). The assay buffer contained 20mM Hepes (pH 7.0), 50mM KCl, 5mM MgCl2, 20mM Na2MoO4, 0.lmg/ml Bovine Gamma Globulin and 0.01% NP40. Compounds were diluted in DMSO and added to the final assay with concentration range from 20µM to 2nM. The polarization degree (mP) value was determined by BioTek Synergy II with background subtraction after 3 hours of incubation at room temperature. IC50 was calculated using Prism software with sigmoidal dose-response curve fitting. ABT-737 was used as reference compound. Such assays, carried out with a range of doses of test compounds, allowed the determination of an approximate IC50 value. Although the inhibitory properties of the compounds of the present invention vary with structural change as expected, the activity generally exhibited by these agents was in the range of IC50 =0.1 – 1000 nM. Biological Example 2: In vitro Anti-proliferation Assay in BCL-2–dependent acute lymphoblastic leukemia (ALL) cell line RS4;11 Cell antiproliferation was assayed by PerkinElmer ATPlite™ Luminescence Assay System. Briefly, the various test cancer cell lines were plated at a density of about 1 × 104 cells per well in Costar 96-well plates, and were incubated with different concentrations of compounds for about 72 hours in medium supplemented with 5% FBS or 10% normal human serum(NHS). One lyophilized substrate solution vial was then reconstituted by adding 5 mL of substrate buffer solution, and was agitated gently until the solution was homogeneous. About 50 µL of mammalian cell lysis solution was added to 100 µL of cell suspension per well of a microplate, and the plate was shaken for about five minutes in an orbital shaker at ~700 rpm. This procedure was used to lyse the cells and to stabilize the ATP. Next, 50 µL substrate solution was added to the wells and microplate was shaken for five minutes in an orbital shaker at ~700 rpm. Finally, the luminescence was measured by a PerkinElmer TopCount® Microplate Scintillation Counter. Such assays, carried out with a range of doses of test compounds, allowed the determination of the cellular anti-antiproliferative IC50 of the compounds of the present invention. The following table lists the IC50 values of certain compounds of the invention. Biological Example 3: mice PK study The pharmacokinetics of compounds were evaluated in CD-1 mouse via Intravenous and Oral Administration. The IV dose was administered as a slow bolus in the Jugular vein, and oral doses were administered by gavage. The fomulaltion for IV dosing was 5% DMSO in 20% HPBCD in water, and the PO formulation was 2.5% DMSO, 10% EtOH, 20% Cremphor EL, 67.5% D5W. The PK time point for the IV arm was 5, 15, 30 min, 1, 2, 4, 6, 8, 12, 24 hours post dose, and for PO arm was 15, 30 min, 1, 2, 4, 6, 8, 12, 24 hours post dose. Approximately 0.03 mL blood was collected at each time point. Blood of each sample was transferred into plastic micro centrifuge tubes containing EDTA-K2 and collect plasma within 15 min by centrifugation at 4000 g for 5 minutes in a 4℃ centrifuge. Plasma samples were stored in polypropylene tubes. The samples were stored in a freezer at -75±15°C prior to analysis. Concentrations of compounds in the plasma samples were analyzed using a LC- MS/MS method. WinNonlin (PhoenixTM, version 6.1) or other similar software was used for pharmacokinetic calculations. The following pharmacokinetic parameters were calculated, whenever possible from the plasma concentration versus time data: IV administration: C0, CL, Vd, T1/2, AUCinf, AUClast, MRT, Number of Points for Regression; PO administration: Cmax, Tmax, T1/2, AUCinf, AUClast, F%, Number of Points for Regression. The pharmacokinetic data was described using descriptive statistics such as mean, standard deviation. Additional pharmacokinetic or statistical analysis was performed at the discretion of the contributing scientist, and was documented in the data summary. Biological Example 4: In vivo Xenograft Studies Compound of Example 3 is selected for in vivo studies in the BCL-2–dependent acute lymphoblastic leukemia (ALL) RS4;11 xenograft model. The CB.17 SCID mice are obtained at age 6-8 weeks from vendors and acclimated for a minimum 7-day period. The cancer cells are then implanted into the nude mice. Depending on the specific tumor type, tumors are typically detectable about two weeks following implantation. When tumor sizes reach ~100- 200 mm3, the animals with appreciable tumor size and shape are randomly assigned into groups of 8 mice each, including one vehicle control group and treatment groups. Dosing varies depending on the purpose and length of each study, which typically proceeds for about 3-4 weeks. Tumor sizes and body weight are typically measured three times per week. In addition to the determination of tumor size changes, the last tumor measurement is used to generate the tumor size change ratio (T/C value), a standard metric developed by the National Cancer Institute for xenograft tumor evaluation. In most cases, %T/C values are calculated using the following formula: % T/C = 100 × ∆T/∆C if ∆T > 0. When tumor regression occurred (∆T < 0), however, the following formula is used: % T/T0 = 100 × ∆T/T0. Values of <42% are considered significant.
